SolvedNeed some help with a X ray mod

Well, after seeing Team Avolition's Nokcraft griefing episode, I realized the idea of making all blocks expect ores slightly transparent to act like a X ray was a good idea. Would someone be able to program a mod to accomplish this? I do not want anything ingame to activate it, just something I can add to the minecraft.jar to always use.
Thanks

There's mods for that: http://www.mpgh.net/forum/384-minecr...x-ray-mod.html
